There is a bug in the current NVidia drivers affects chimera stereo -- all of the 197.X don't work.  If you downgrade the driver to version 191.87, it will work.

Hi,
I'm helping Chinese Academy of Sciences test 3D Stereo display with your Chimera-1.4.1.
We are using the Samsung Syncmaster 2233 monitor, Nvidia 3D Vision kit (transmitter plus glasses). 
I'm able to open the software. When I select, tools->camera->sequential stereo, the application will enounter an error and exit.
Attached are the snapshots of the error message and details of our computer.
